Background correction is a first step for DNA array data processing; however, current methods for background correction have disadvantages. In this thesis, I propose a mixture model to facilitate the background correction for DNA array data generated by ImaGene. The corresponding software is also provided.enAvailable to the World Wide WebDNAArrayUVic Subject Index::Sciences and Engineering::MathematicsThesis
